Head of the Israeli Defense Ministry's political-security department Amos Gilad met yesterday with chief of the Egyptian intelligence Omar Suleiman to discuss the terms of the truce in the Gaza Strip. For his part, the Israeli Minister of Defense Ehud Barak has threatened to launch new attacks on the tunnels between southern Gaza Strip and Egypt, claiming that some of them are used for smuggling weapons. Hamas has denied the postponement of its delegation's visit to Cairo, adding that there was no specific date for the visit. Gilad's talks have focused on the tangible actions that should be taken to prevent arms smuggling across the border between Egypt and the Gaza Strip, well-informed sources said. In a televised statement yesterday, the Israeli Defense Minister Ehud Barak said the Israeli forces have destroyed 51 tunnels during the military operations on Gaza. Barak's statement came after reports on the return of work in dozens of tunnels not destroyed during the Israeli operations.
